The Earth Observing System (EOS) Clearinghouse (ECHO) has been operational for two years and enables a "marketplace" of
science data and service providers, and consumers. To accomplish this goal, ECHO provides two registries. The first is a
registry of metadata that is updated on a regular basis by the data providers. These metadata describe science content and
data acquisition details about the data holdings. The second is a registry of services. Together these registries support
discovery, access and delivery capabilities.
ECHO makes these available to clients so that clients appear to have all the metadata in their system without the burden of
managing it all. ECHO also offers its clients a single interface for placing orders, and then brokers them on behalf of the
users. ECHO provides some user account management capabilities. In the future, ECHO will broker service and data
transactions. This all serves to simplify client development and streamline data and service access by end users. It also
alleviates the burden on the scientist of having to find and apply data services to the data. Scientists can focus their
time on their jobs of analysis and research. ECHO also provides tools to help in use of the APIs.
This presentation discusses the capability and resources available to help providers of data and services, client developers
and applications developers in using ECHO as their data and service access infrastructure.
